Wind spectra and escape response of the cockroach.
Do cockroaches `know' about fluid dynamics?

Experiments with random noise stimulus on escape response system of
American cockroach revealed rather unexpected results. Firing rates of
giant interneurons, that convey essential information about wind
stimulus, strongly depends on the spectral shape of the random noise
stimulus, and do not depend on overall power of the stimulus. A
neuroethological relevance and a simple model of this phenomenon are
proposed. Some results on information calculation will be presented.
